AI Technical Summary

Technical Problem

In the existing technology, the wear and overheating seizing problems of the screw pair of the screw press caused by sliding friction are difficult to solve effectively. Traditional grease lubrication is uneven, has poor heat dissipation, and is wasteful and causes environmental pollution.

Method used

The lubrication device, which adopts a dual oil return path design, achieves efficient, continuous, and circulating lubrication of the friction pair between the main screw and the main nut through the main oil inlet pipe, distributor, branch oil inlet pipe, slide block return pipe, and gland return pipe. This ensures that the lubricating oil is evenly distributed and promptly recovered, avoiding waste and pollution.

Benefits of technology

It significantly improves the reliability and service life of equipment operation, reduces lubricant consumption, conforms to the concept of green manufacturing, prevents local wear and thermal damage, and improves transmission smoothness and reliability.
